When we do this of necessity the world will be a darker place.
Not necessarily.
Japan & Germany have abandoned their formerly megalomaniac adventures.
India just had a election with 500 million voting.
They elected equivalent of the US Tea party, the BJP.
So India will move more towards capitalism.
Most of Europe has minimum military manpower to be able to cause any problems.
Only country to watch out for trouble is China.
However I just came back from a tour of South East Asia,
and I observed emergence of strong economies in many places.
Taiwan, S. Korea, Singapore have strong economies. Viet-Nam,
Thailand & Malaysia will not tolerate China hegemony.
China is now all about expanding economic reach abroad.
Russia can gobble up small chunnks of former USSR satellites, but does not have the economy to try world dominance.
Africa has problems created by their own. Such as the crimes allowed by Boko Haram in Nigeria by a corrupt government. So why should US taxpayers fix every problem which crops in these countries due to their fault?
